Bentall`s operation for repair of annuloaortic ectasia has been associated with postoperative bleeding and with false aneurysm of the anastomotic site between the coronary orifice and composite graft.Among 5 cases, 2 cases have been operated direct anastomosis between coronary artery and vascular graft.Remained 3 cases have been operated with doughnutlike Teflon felt buttress.The technique of sandwiching the freed button of aortic wall bearing the coronary artery ostium between an outer Teflon felt doughnutlike buttress and the inner composite graft provides a leak-proof anastomosis.We experienced one case reoperation for bleeding at coronary anastomotic site above method.

아산재단 서울중앙병원 흉부외과에서는 1993년 10월부터 1997년 4월 사이에 대동맥륜대동맥 확장환자에서 37례의 Bentall술식을 시행하였다. 환자군의 술전 호흡곤란 정도는 NYHA Class I이 4례, Class II가 10례, Class III가 20례, Class IV가 3례였다. 수술은 대동맥박리증이 동반된 경우 초저체온법(식도체온: 11.8$\pm$1.6!), 완전순환정지, 역행성 대뇌관류법을 시행하였다. 37례 모두 병변이 있는 대동맥벽을 대부분 제거하고 복합이식편이나 대동맥 인조혈관 및 인공판막을 이용하여 상행대동맥과 대동맥판막을 치환하였고, 관상동맥편을 인조혈관에 직접 연결하였다. 수술결과는 합병증은 7례 발생하였으며(18%), 수술사망은 없었으나 뇌혈관 발작으로 인한 1례의 만기 사망이 있었다(2.7%). 퇴원후 추적기간은 1개월에서 36개월까지였으며 평균 9.6개월였다. 결론적으로 대동맥륜대동맥 확장의 수술에 있어 Bentall술식은 안전하고 좋은 수술이라 할 수 있다.

Most patients having annuloaortic ectasia are associated with marked dilatation of the sinuses of Valsalva and the aortic annulus as well as the huge aneurysm of the ascending aorta. A 19 year old male patient complaining of tightness on left posterior chest wall underwent cardiac angiography in which demonstrated annuloaortic ectasia with ascending aortic aneurysm and aortic insufficiency. The patient had corrective operation replacing the ascending aorta and aortic valve with a composite graft[Dacron prosthesis containing a Bjork-Shiley aortic valve] within the aneurysmal sac. The coronary orifices were anastomosed to the tubular Dacron prosthesis [30 mm in diameter] by means of a second smaller Gore-Tex tube [8mm in diameter]. The aneurysmal sac was trimmed by removing the redundant wall and then wrapped outer wall of the Dacron prosthesis. Postoperatively, mediastinal bleeding was temporarily observed in the operative day and satisfactory blood pressure was maintained with small dose of dopamine. One week later, large amount of serous effusion was drained out of the retrosternal space making partial disruption of the skin which was healed well by daily local dressing. The patient discharged in good condition on postoperative 29th day with no residual complications and is doing very well on the 4 months follow-up.

Between November, 1981 and July, 1989, 4 patients, 3 male and 1 female patients ranging in age from 36 to 45 years, were operated on for aortic insufficiency associated with uncomplicated annuloaortic ectasia. All patients were in New York Heart Association class III. Two patients had clinical stigmata of the Marfan syndrome. The surgical treatment consisted of. supracoronary replacement of ascending aorta with vascular graft and replacement of the aortic valve in our first case. and composite graft replacement of the ascending aorta and aortic valve with reimplantation of the coronary arteries in subsequent 3 cases. Our first patient developed aneurysm of proximal aorta and pseudoaneurysm of distal aortic anastomosis 5 years postoperatively. One patient among the three patients with Ben-tall operation, died of ventricular fibrillation and myocardial failure during immediate postoperative period. Remaining 2 patients were in NYHA class I with follow-up of 16 months and 20 months respectively.

Marfan 증후군과 같은 대동맥 질환의 경우 대동맥동 및 대동맥륜의 점진적인 확장 및 변형이 발생하여 대동맥판막의 폐쇄부전을 초래한다. 이런 경우 대부분 상행대동맥과 대동맥 판막을 composite graft의 형태로 치환하고 여기에 관상동맥을 문합하는 술식이 적용되어왔다. 본 증례는 Marfan 증후군이 동반된 22세 남자 환자로 대동맥 근부 확장과 승모판막 부전이 있었다. 수술은 대동맥 판막 및 좌심실유출로의 일부를 보존하면서 상행대동맥 및 Valsalva동의 동맥류를 제거하고, 대동맥 판막 및 관상동맥을 인조혈관에 다시 문합하는 술식을 적용하였다. 술후 심초음파 검사상 대동맥 판막의 기능은 정상이었다. 대동맥륜 확장증에 있어서 대동맥 판막이 정상적인 해부학적 구조를 가진다면 이상의 술식을 적용함으로써 자신의 대동맥 판막은 보존하면서 대동맥 근부를 치환할 수 있으리라 생각된다.

Coronary artery ectasia (CAE) is defined as the dilation of a segment of a coronary vessel to at least 1.5 times the diameter of its normal adjacent segment. Mean platelet volume (MPV) plays a role in acute coronary syndromes, with high MPV correlating to poor prognosis for acute thrombotic events and CAE. Several studies investigated the relationship between MPV and CAE, resulting in conflicting results. These results led us to systematically review all studies investigating the relationship between MPV and ectatic heart diseases by performing a meta-analysis study in order to report a unified result. This meta-analysis study investigated all case-control articles examining the relationship between MPV and CAE. All studies in the following databases published until January 31, 2018, were investigated: Science Direct, Scopus, PubMed, Google Scholar, and Web of Science. Following a quality control evaluation, 14 articles, all of which were published following studies performed in Turkey from 2007 to 2016, met the criteria for study inclusion. After pooling the results from all of the articles, a total standardized mean difference (SMD) value of 0.584 (95% CI, 0.219, 0.95) was obtained using the D+L pooled SMD, indicating a significant difference (P=0.002) between the two groups, with higher MPV values in ectatic patients when comparing to healthy individuals. Therefore, increased MPV levels were significantly related to CAE, suggesting that platelets, with their inflammatory and thrombotic activities, play a role in this disease. Therefore, anti-platelet and anti-inflammatory therapies may be effective in treating CAE.

From January 1991 to January 1995, 11 patients with aortic diseases underwent various surgical repairs. The age at operation ranged from 26 years to 63 years[ mean=50.9 years . The disease entities included 8 aortic dissections[ type I in 4, type II in 2 and type III in 2 cases , 2 Marfan`s syndrome with annuloaortic ectasia and 1 desecending thoracic aortic aneurysm The operative procedures we tried were 3 Bentall`s operation, 5 graft replacement of ascending aorta, and 3 graft interposition in descending thoracic aorta.Overall hospital mortality rate is 36.3%[4/11 . And causes of death are pump weaning failure in 2 cases and multiorgan failure in 2 cases. It was that 2 sternal dehiscence & mediastinitis, 1 acute renal failure, 2 hypoxic brain damages and 2 postoperative psychosis were complicated. Recently we tried surgical repair of aortic dissection five out of 6 cases using total circulatory arrest with deep hypothermia at 14$^{\circ}C$. Total circulatory arrest time ranged from 18 to 26 minutes[ mean 22.2 minutes , and mean aortic cross-clamping time was 48.2 minutes. One of 5 patient died on the 7th postoperative day due to multiorgan failure. Mortality of patients with TCA was 20%[1/5 , and it of remainders was 50%[3/6 . Our result for surgical repair using total circulatory arrest with deep hypothermia is satisfactory on the basis of our clinical data.

우심실 저형성 환자에서 심실중격결손과 대동맥판막 폐쇄부전 및 대동맥판륜 확장증이 동반된 경우는 매우 드물다. 저자들은 우심실 저형성 환자에서 심실중격결손, 대동맥판막 폐쇄부전 및 대동맥판륜 확장증이 동반되어 composite graft를 이용한 근부치환술을 시행한 증례를 보고한다. 환자는 19세 남자로 심장초음파 및 심도자 검사에서 직경 2 cm크기의 막성 심실중격결손과 심한 대동맥판막 폐쇄부전증, 그리고 대동맥판륜 확장증이 동반되어 있었으며 우심실은 bipartite 형태로 심한 저형성을 보였고 Qp/Qs는 1.2였다. 수술소견 상 우관상 및 비관상 판첨 변연부 길이의 현저한 확장, 판첨의 비후와 수축, 그리고 교련부의 융합 및 석회화가 있었다. 수술은 대동맥근부를 통해 자가 심낭 패취를 이용한 심실중격결손 폐쇄술 및 composite graft를 이용한 button Bentall 술식과 우심실 유출로 부위의 비후된 근육을 절제하여 주었다. 환자는 수술 직후 일시적인 심폐기 이탈의 어려움이 있었으며 술 후 14일째 특별한 합병증 없이 퇴원하였다.
